[V5] Go in production, few questions

[Reptiluka]

Hi !

Simple question here,
if I want to deploy in production, should I simply run : npm run build,
and, run npm install upload the /build/ folder, and then, run npm start on that ?

Also, during the website is up and running, how I update the site ?
Should I turn off the website, or upload new file and run migration without stop the server ?

Thank you !
